Impact of Adapted Physical Activity on Joint Pain Induced by Hormonotherapy in Adjuvant Breast Cancer Treatment: APAISE Study Protocol

Breast cancer is the most common cancer in women and approximately 80% of patients will receive hormone therapy. If survival rate after breast cancer patients is the most important, their treatment, induces strong side effects on quality of life, including joint pain which is encountered by one woman in two. These joint pains are likely to reduce compliance with the treatment and consequently impact survival. In this context, this work aims to evaluate the potential benefit of adapted physical activity to relieve pain and its impact on daily functions. The APAISE protocol, described in this article, is a prospective observational study carried out in women operated on for breast cancer and suffering from pain induced by hormone therapy (approximately 50 women followed up in 2 living areas). The main objective is to evaluate the evolution of pain in the context of an adapted physical activity supervised by a sports educator over a period of 3 months. In addition to pain and its interference, the other parameters studied are quality of life, therapeutic compliance and the level of physical activity. All these indicators will be measured at inclusion, at 3 months and at 6 months. In addition to an expected benefit on the well-being of patients, the results should shed light on the links between physical exercise and pain and in the long term reinforce recommendations in terms of physical activity in breast cancer patients.
